    Phoronix: Working Towards Lower OpenGL Driver Overhead

    Today at the Game Developer's Conference was an interesting session with OpenGL developers from Intel, AMD, and NVIDIA jointly talking about reducing OpenGL driver overhead...

    AMD's changing Linux strategy doesn't tell us much. They change their minds when it comes to Linux support every six months.

      i agree

      i like to see they supporting more and more opensource driver... and what about mantle? another fail?

        there is no point in mantle on linux. right now, their opengl is still subpar and i would prefer them fixing that 1st and then add another unfinished layer. adding subpar mantle which would be probably beta until 2019 would just add to bugs on amd unless you prefer having buggy gl+beta mantle

          i don't care about mantle =D

            I'd rather see some consistent behavior from them. It doesn't matter if it's negative or positive, I just want them to make up their minds already.

              i give up from amd gpu long time ago, they have the worst support! and its not only in linux side, at least radeon r600 is in good shape for old apu's

                What are you talking about? Their open source drivers have had consistent support for well over six months, and soon to be an entire year of consistent improvement. It's a lot better than what NVIDIA is doing.

                  Yet it is the GPU of choice for BitCoin mining and a number of other GPU compute uses.

                  I'd be the first to admit AMD has had driver issues, but it looks like they have seen the open source light and have effectively made it possible for anybody to write drivers for their hardware. On the other hand they have put together a very unique program which ought to make GPU far more interesting.

                    they need to put better support in opensource driver, more people working like intel do, in my opinion they need to forget fglrx driver and put all resourses in radeon

                      Wow, seeing those numbers in comparison to "naive" (whatever that means here) Direct3D11 really makes you wonder why engine architects aren't jumping on GL4.3. Especially with things like VirtualReality where very high framerates across two rendered screens are indispensable.

                      The more I read into this though, the more it seems like the opaque work of the driver is thinning, and you more or less end up managing most of the GPU resources yourself (manual buffer access fences, texture allocations via sparse arrays of arrays etc.).

                        The truth sometimes gets in the way when trying to promote your favorite product. AMD is doing lots of things right. Unfortunately these right things often take a long time to realize fully, sometimes impatience is a factor.

                          Guys, nothing discussed in this presentation are part of AMD's new Linux driver strategy, that I am still fathoming and will be writing about in the next day or two... Off now to another dinner with AMD to discuss this matter.

                            And before that they fired 90 percent of their Linux developers and put their proprietary drivers on life support for many months. Then they decided that open source is they way forward. Now, they're again fixing bugs in their closed source drivers (check the vogl blog) with the help of Valve. Apparently, they even announced mantle and trueaudio(?) Linux support, etc. This is what I l call a severe case of "jack of all trades and master of none".


                            Anyway. We'll see what they have planned this time I presume in several days. I have nothing against AMD. I just wish they'd be more consistent with their Linux endeavors.

                              Source?

                              Source where they ever stopped?

                              Source about it being on linux?

                              and trueaudio(?) Linux support, etc.
                              That's no surprise, they usually support their hardware through the fglrx driver. It would be surprising if they didn't plan to support it.

                              This is what I l call a severe case of "jack of all trades and master of none".
                              Absolutely, and you can criticize that, but they've been like that for years now. I don't see anything changing over the past 3 years, let alone the last 6 months.

                              I just wish they'd be more consistent with their Linux endeavors.
                              It's this "consistency" you speak of that i don't understand. They have been consistent. Maybe you meant you wish they would do other things and they aren't doing them? Or just do them better?
